QD could do with more explanation, maybe like so?

            ENGINE      BUSY                         E   Q   W MI_SEMA MI_WAIT
>      Render/3D/0    60.47% |███████████▍       |  28   0   1      0%      0%

Render/Compute?

Another visual break after QD?

  Render/Compute/0    60.47% |███████████▍       |  28   0   1 |    0%      0%
